+     "Anonip masks the last bits of IPv4 and IPv6 addresses in log files.
+That way most of the relevant information is preserved, while the IP address
+does not match a particular individuum anymore.
+
+Depending on your Web server, the log entries may be piped to Anonip directly
+or via a FIFO (named pipe).  Thus the unmasked IP addresses will never be
+written to any file.
+
+It's also possible to rewrite existing log files.
+
+Anonip can also be uses as a Python module in your own Python application.")
